Abstract (en)
[origin: US2013207022A1] Mixtures of select neopentyl polyol esters are found to be highly miscible with the refrigerant R-32 over a wide temperature range. Working fluids are provided comprising R-32 and a polyol ester lubricant composition having a kinematic viscosity at 40° C. of from 32 to 120 cSt, said lubricant composition comprising C5-10 alkylcarboxy esters di-pentaerythritol wherein at least 40 mol %, typically more, of the alkylcarboxylate groups of the alkylcarboxy esters are pentanoyl groups.
